Description

technical field [0001] This patent relates to a safety auxiliary equipment for a stage, in particular to a safety protection support column for a lifting platform. Background technique [0002] With the improvement of people's living standards, the demand for spiritual civilization has become more and more vigorous, especially for small stages, miniature stages, and community stages. The introduction of stage machinery is a shortcut to upgrade the current small stage, miniature stage and community stage. The introduction of the stage with mobile modules can greatly enrich the expressive force of the stage, improve the form of stage expression, and create a better stage in a limited space. Stage effects, therefore, it is imperative to develop a stage with mobile modules.
